Augustyn Jakubisiak (1884-1945), Polish priest, philosopher and theologian, undertook polemics with Jan Łukasiewicz, whom he knew personally. A dispute concerning the so-called logistics (mathematical logic) and its relationship with philosophy developed between the two. The most important arguments were laid out, primarily in the following works: in the case of Jakubisiak, in the book From Scope to Content and in the case of Łukasiewicz, in the texts Logistics and Philosophy and In the Defense of Logistics. Jakubisiak criticized logistics for its anti-metaphysical, anti-theological and anti-religious attitude, which was based on neo-positivist philosophy, and led, in consequence to atheism. He also claimed that one should focus on what is concrete, avoiding idealization and abstraction (meaning the content of concepts, not their scope).
